LEWIS HAIJIJOCK NASH, OF SOUTH NRWALK, CONNECTICUT.

WATER-METER.

To all whom it may concern:

Be it known that LLnwrs HALLoCK NASH, a citizen of the United States, residing at South Norwalk, in the county of Fairfield and State of Connecticut, have invented certain new and useful 'Improvements in later-Meters, of whichthe following is a specification. Y

My invention relates to new and useful improvements in water meters, and the invention consists in the construction and arrangement of parts, and their aggroupment in operative combination to be more fully described hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my invention in the accompanying drawings to be taken as a part of this specification and wherein Figure 1 is a vertical central section through a structure embodying my present invention. Fig. 2 is a horizontal sect-ion on the line 2-2 of Fig. 1. Fig. 3 is a horizontal section on the line 3-3 of Fig. 1. Fig. 4 is a vertical central section through a meter embodying my invention, part of the piston casing being in elevation and part broken away. Fig. 5 is a view similar to that of Fig. 4 but showing the piston in another position. Fig. 6 is a plan View of a piston employed in the shown embodiment of the inventlon.

Referring to the drawings by characters of reference,

1 designates the base portion of a meter casing structure upon which the parts of the measuring mechanism, its driving means and the casing therefor 'are mounted, said base being circular in plan, as shown in Fig. 2, and having a vertical circumferential wall 2, formed with a horizontal inwardly projecting annular iiange 3. This base is provided with an inlet nipple :t and an outlet nipple 5, adapted to be connected to the pi e line through which passes the flow to lie measured, and in said base is a vertical partition G separating the inlet from the outlet. This partition forms a chord with the circular ,wall of the casing base, so that the inlet side of the base is in the form of a segment of a circle, and said partition divides said base into inlet and outlet chambers 7 8.

Arra ed in the base 1, above the bottom thereof, 1s a screen 9 of sheet metal having Specification of Letters Patent.

greater than the inlet portion of the casing i and conforms in contour thereto, so that when it is forced down into place, it will` frictionally-und yieldingly engage the in` terior wall of the inlet suie oi' the casing which frictional engagement will serve to snugly hold the screen in place.

11 designates a base plate for the piston casing said plate being arranged concentric with the base 1, and supported on the iiange 3, by means of ears 12 integral. with the plate l0 said ears being secured to said flange by screws 13. This plate 11, throughout that portion of its area over the inlet side of the base 1, is spaced inward from said fiange 3 so as to leave a space for the upward flow of water from the inlet. The plate is provided with an extension or lobe 14, extending over the outlet chamber 8, which extension is provided with a port 15, communicating with the outer chamber. In its upper face the plate has a radial relief duct 18, opening at'its outer end into the port 15. The plate 11 is also formed with a central concave bearing seat 19, for the ball of a wabbling piston to be presently described, said seat having an opening 20, communicating with the inlet ortion of the base 1. The piston casing is completed by a circular dome 21, having an inner curved side wall Q2, which at one side is provided with a chambered extension 23, extending over the extension 14, of the plate 11, and opening through the port 15, to provide communication between the outlet and the interior of The lower edge of Athe circular wali 22 of the dome is sealed in a circumferential rabbet Q4 in the upper face of the plate 11, as is also a bridge piece Q3". forming a continuation of the main wall of chamber 21, extending across the bottom of the extension 23 and seated in the said rabbet 24 and projecting above the upper face of the plate 10. It will be seen that the arrangement is such that a tight joint is formed between the plate 11 and the dome 21 at all points except the rent. or duct 18 and the communication between the chamber 23 and the port 15. The dome 21 is formed with a conical desis on in in: :inimiliortion forming the interina' nl' ilw piston raging with a conical 'llie lnlate lil and lomo l iolin il iletaniallr iri'iilar rl'ininlaer having a Hat iintinn anni minimi! tot Haring; upward aml milf-JMJ fron tlie wim-i'.
